I used the Rustoleum Professional on the garage floor about a month ago. Lowes had it in a kit. 1.25 gallons of color & 1.25 gallons of hardner, a pack of color flakes, 2 small packets of citric floor etch, a roller screen & it all came in a 5 gallon bucket. I used 2 kits on my 875 sq ft floor, and had almost a half gallon left over.
I top coated with 2 kits of the Rustoleum Clear garage 2 part epoxy and used about half of the anti skid granules (?) that they supplied. Am very happy with the way it turned out. Its highly reflective, not slippery when wet and so far has proven to be pretty tough. Without the clear, the finish was very flat.
Lessons learned 1- I was not happy with the floor texture after using the citric acid etch, was gonna buy muriatic acid & re-etch, but before I did I called the Rustoleum help line. Tech was pretty adamant about NOT using the muriatic acid. He said that the concrete would etch too deeply & 1 coat would not cover well. I described the texture ( 150-200 grit sandpaper) and he said that seemed about right. I was still skeptical so he sent me 2 more packets of the etch. Re-etching didn't change the texture much. But in the end, the epoxy stuck & covered well.
2- I mixed the entire mixture at once, it took about 2 hours to do the floor & the epoxy still had plenty of pot life left in it. 75 degrees when I started actually applying epoxy & close to 90 by the time i got done.
3- Put it on pretty thick. I used a plastic backed paint roller from HD ( about $5.00 each) to apply the epoxy. BTW - No shedding at all. With each roller I covered about 5-6 sq ft of floor, this was probably too thin a coat as I had plenty left over. I did a 32 inch strip acrossed the garage & then came back in the other direction with another 32 in strip. After every 3rd roller of epoxy I spread ( tossed in the air) the flakes over what I had done. I used between 1/2 & 3/4 of the supplied flakes.
4- Clear went on easy, Mixed the anti skid in the the epoxy and applied. Must constantly stir it to keep the granules from settling out. Not applied near as thick as the color and I had just enough to finish the floor.
5- Plenty of ventilation, I had a garage door at each end open and a 24" inch fan blowing thru a side window. Both my wife & son said they could smell the fumes outside the garage.
Hope that my novella helps in some way.
